Answer:
Initial number of trees were 204.
Step-by-step explanation:
555 must be a typo error. The question will not produce correct answer. I worked out with 55 but the answer is wrong. So, the number is 5.
Lets say MacDonald removed 5 orange trees from his farm.
Let t be the initial number of trees
After removing 5 trees, the remaining left are t-5 trees
As given - Each of the remaining trees produced 210 oranges for a total harvest of 41790 oranges. This means

Solving for t:



t = 204
So, initial number of trees were 204.
We can check this :

Working with 55 we get the wrong answer:



t = 144
We can check this : 
(wrong)
I think the answer is (0,2)
<span>27m^3+64n^3 is an example of the sum of two cubes.
There's a factoring formula for that: a^3 + b^3 = (a + b)(a^2 - ab + b^2.
Thus, </span><span>27m^3+64n^3 = (3m + 4n) ( 9m^2 - 12mn + 16n^2).
Could also find this out by dividing 3m+4n into </span><span>27m^3+64n^3.</span>
